Modification of search subject in predictive search sentences

ABSTRACT

A computer implemented method for modification of search subjects in a set of predictive search terms in which a set of search terms from a user is received. One or more sets of predictive search terms generated and one or more search subjects within the one or more sets of predictive search terms is identified and communicated to the user. A modified search subject is received from the user in response to presenting the use with an option to modify the one or more search subjects. Furthermore the modified search sentence comprising the set of search terms and predictive search terms or modified search terms is searched.

BACKGROUND

The present invention relates generally to the field of computer systems, and more particularly to semantic analysis and predictive online searching.

Functional efficiency is an important part of any online search engine. Functionality of a particular search engine may vary by several factors including the efficiency of predictive search terms.

Through the use of a user interface, such as a user interface of a web browser, a user can access web pages that contain information. One technique for finding specific web pages on the Internet or an intranet is through the use of a search engine. Search engines typically maintain an index of millions or billions of web pages and provide a web browser interface that can be used to search and access web pages by keywords and text phrases in the web pages. Some well-known search engines include Google™ and Yahoo!®.

Autocomplete, or presenting a set of predictive search terms, is a feature in which a search engine predicts the rest of a word a user is typing in a search input field. In graphical user interfaces, users can typically accept one of several predictive search terms. This feature speeds up human-computer interactions.

SUMMARY

It may be desirable to implement a method, system, and computer program product which considers various aspects of use of a particular search phrase in order to give users an option to customize predictive search terms.

An embodiment of the present disclosure provides a method for modification of search subjects in a set of predictive search terms. The method includes receiving search terms from a user, generating predictive search terms based on the set of search terms, identifying search subjects within the predictive search terms, communicating predictive search terms to the user, receiving a modified search subject from the user in response to presenting the user with an option to modify the search subjects, and searching based on a modified search sentence. The method may include communicating a list of predictive search subjects to the user. The method may include replacing search subjects with blank spaces. The method may further include receiving a text input from the user and determining the modified search sentence based on the text input. The method may include conducting an online search based on the modified search sentence and communicating the search result to the user. Furthermore, the method may include identifying one or more search subjects based on determining a set of search domains for the set of search terms, identifying a word corresponding to the set of search domains, and determining the one or more search subjects based on the commonality of the search domains. The method may also include identifying search subjects by generating tokens based on the predictive search terms, semantically analyzing the tokens, determining the semantic commonality among the tokens, and determining the search subjects based on the semantic commonality.

DETAILED DESCRIPTION

While the present invention is particularly shown and described with respect to preferred embodiments thereof, it will be understood by those skilled in the art that changes in forms and details may be made without departing from the spirit and scope of the present application. It is therefore intended that the present invention not be limited to the exact forms and details described and illustrated herein, but falls within the scope of the appended claims.

The present invention may be a system, a method, and/or a computer program product. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention.

The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire.

Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.

Computer readable program instructions for carrying out operations of the present invention may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++ or the like, and conventional procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present invention.

Aspects of the present invention are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions.

These computer readable program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks.

The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks.

The flowchart and block diagrams in the figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.

FIG. 1A is a schematic block diagram depicting a computing environment 100 for a Predictive Term Modification Program. In various embodiments of the present invention, computing environment 100 includes a computer 102 and server 112, connected over communication network 110.

Computer 102 may include a processor 104 and a data storage device 106 that is enabled to run a Predictive Term Modification Program and a web browser 116, in order to display the result of a program on server 112, such as, Predictive Term Modification Program 108 communicated by communication network 110.

Computing environment 100 may also include a server 112 with a database 114. The server 112 may be enabled to run a Predictive Term Modification Program 108. Communication network 110 may represent a worldwide collection of networks and gateways, such as the Internet, that use various protocols to communicate with one another, such as Lightweight Directory Access Protocol (LDAP), Transport Control Protocol/Internet Protocol (TCP/IP), Hypertext Transport Protocol (HTTP), Wireless Application Protocol (WAP), etc. communication network 110 may also include a number of different types of networks, such as, for example, an intranet, a local area network (LAN), or a wide area network (WAN).

It should be appreciated that FIG. 1A provides only an illustration of one implementation and does not imply any limitations with regard to the environments in which different embodiments may be implemented. Many modifications to the depicted environments may be made based on design and implementation requirements.

The computer 102 may communicate with server 112 via the communication network 110. The communication network 110 may include connections, such as wire, wireless communication links, or fiber optic cables.

Computer 102 and server 112 may be, for example, a mobile device, a telephone, a personal digital assistant, a netbook, a laptop computer, a tablet computer, a desktop computer, or any type of computing device capable of running a program and accessing a network. A program, such as a Predictive Term Modification Program 108 may run on the client computer 102 or on the server 112. It should be appreciated that managing program 108 has the same component and operation methods regardless of whether it is run on the server 112 or computer 102. Therefore Predictive Term Modification Program 108 applies to a program implemented within the environment of the computer 102 and/or implemented within the environment of the server 112 interchangeably.

Referring now to FIG. 1B, the components of the Predictive Term Modification Program 108, are illustrated. Predictive Term Modification Program 108 comprises 3 modules: receiving module 118A, identification module 118B, and interface module 118C. Receiving module 118A may receive terms to be searched from a user, communicate the search terms to a search engine, and receive predictive search terms from the search engine (based on the search terms). Identification module 118B may identify a search subject within the predictive search terms. Interface module 118C may display a user interface which indicates the search subject to the user, present the user with an option to modify the search subject search term, receive a modified search subject, and display a modified search sentence based on the user's modifications.

For example, in an embodiment, a set of words such as “what are the” is received by the receiving module 118A. Receiving module 118A may communicate these search terms to a search engine online displayed on web browser 116 on a computer 102. Receiving module 118A may also receive the predictive search terms such as: “What are the books written by John Grisham”, “What are the books written by Steinbeck”, “What are the books written by Shakespeare”, “What are the albums of the Beatles”, and “What are the albums of Justin Bieber” from the search engine server. Identification module 118B may analyze these predictive search terms and identify the last word as the search subject. Furthermore, interface module 118C may display: “What are the books written by ______”; receive the word “Hemingway” from the user, display the modified new search sentence (“what are the books written by Hemingway”), and communicate the new modified search sentence to the online search engine.

FIG. 2 is flowchart, which in conjunction with FIG. 3, depicts the operational steps of a method 200 for a Predictive Term Modification Program 108, in accordance with an embodiment of the present disclosure. According to the present disclosure, the method 200 includes modification of a search sentence: “what are the books written by Hemingway”.

In reference to FIGS. 1A, 1B, 2 and 3, steps of the method 200 may be implemented using one or more modules of a computer program, for example, the Predictive Term Modification Program 108, and executed by a processor of a computer such as the computer 102.

At 202 and 204 operation of the receiving module 118A is depicted. Referring now to block 202, the receiving module 118A may receive a set of words from a user or an electronic input source for use in a search, using an online search engine. Receiving module 118A may receive the word(s) from a user or a computer implemented system. Non-limiting examples of an input source may be spoken words, typed words, or inputting a corpus electronically from a computer implemented source such as an electronic device (e.g. cell phones, tablets, or other electronic devices with speech recognition programs). Receiving module 118A may also communicate the words received to a search engine. Furthermore, receiving module 118A may receive a set of predictive search terms from the search engine.

In the present embodiment, receiving module 118A receives words for searching from a user. The user may type in the words on a computer keyboard (i.e. electronic input source). In the present embodiment, receiving module receives the word “what are the” from the user along with instructions to search those words with a google search engine (FIG. 3, sentence 316). It must be noted that the user typing words on a search bar may be treated as instructions to search for the words with an online searching tool.

It must also be appreciated that for the purposes of this invention, a search sentence includes the grammatical meaning of a sentence (i.e. a sentence is a linguistic unit consisting of one or more words that are grammatically linked. A sentence can include words grouped meaningfully to express a statement, question, exclamation, request, command or suggestion) or a sentence fragment or an incomplete sentence (i.e. an incomplete sentence, or sentence fragment, is a set of words which does not form a complete sentence, either because it does not express a complete thought or because it lacks some grammatical element, such as a subject or a verb).

Receiving module 118A, in the present embodiment, communicates the received words to the google search engine server. In the present embodiment, receiving module 118A also receives a set of predictive search terms from the google search engine server. In this embodiment the predictive search terms are as follows:

“What are the books written by John Grisham”;

“What are the books written by Steinbeck”;

“What are the books written by Shakespeare”;

“What are the albums of the Beatles”; and

“What are the albums of Justin Bieber”.

At 206, operations of the identification module 118B is depicted. Identification module 118B may, using the predictive search terms, received by the receiving module 118A, identify a search subject within the predictive search terms. In other words, the search subject is the subject of a predictive search terms which propels the search results and the answer to the simple question of “what is the user searching for?” For example, in an embodiment, in the question “where do you keep your milk?” the word “milk” is the search subject because the word milk is the vital part of this query and what the user is asking for. By changing the word “milk” to “cups” the response to this question will inevitably yield a different answer.

In one embodiment, identification module 118B may identify the search subject upon information received from the search engine server. The search engine server may point towards search domains. Search domain is a possible search sites to use for searching using the search term. These search domains may indicate the search subject. Identification module 118B may receive the search domains from the search engine server. In various embodiments, “what is the email of ______” may result in a search in some rolodex or a yellow pages, “what books did ______ write” may result in a search in Wikipedia, or “what is the status of ticket to ______” may result in a query to a ticket-purchasing application or ticket providing sites. Therefore identification module 118B may use the search domains to identify the search subject by identifying the commonality of categories between the sites by analyzing the commonality of the indexes and categories of all the sites. For example, in one embodiment, when the search term of “what is the status of flight to Zurich” results in a query of many airport sites, identification module 118B may identify that the word “Zurich” is the search subject because all search domains have cities and destinations in common. Because the word “Zurich” is a city/destination, it is consistent with the commonality among the search domains; based on this information, identification module 118B may identify “Zurich” as the search subject. In one embodiment the search domains sites are included within the predictive search terms as metadata and identification module 118B analyzes said metadata.

In another embodiment, the search engine can progressively retrieve search results and analyze the results to dynamically identify the search subject. Identification module 118B may, in order to process the natural language, decompose the received predictive search terms into tokens and may use the tokens to determine the search subject. A token is a short piece of text or a fragment of a sentence usually comprising of words. A word is a smallest element that may be uttered in isolation with semantic or pragmatic content (i.e. literal or practical meaning). Non-limiting examples of a token include nouns, adjectives, and pronouns. Identification module 118B may analyze each token for various semantic properties. Identification module 118B may analyze the tokens and determine the search subject based on the common semantic properties of each token, sentence structure of the predictive search terms, and common properties of the tokens among all predictive search terms. For example, in one embodiment, the predictive search terms may comprise the following:

What to expect during month 1 of pregnancy;

What to expect during month 2 of pregnancy;

What to expect during month 9 of pregnancy;

After decomposing the terms into token and analyzing these tokens, identification module 118B may determine that the month number is the common token among all predictive search terms and therefore the search subject (i.e. a search subject search sentence of what to expect during month ______ of pregnancy).

In the present embodiment, identification module 118B analyzes the predictive search terms. The predictive search terms are as follows:

“What are the books written by Hemingway”;

“What are the books written by Steinbeck”;

“What are the books written by Shakespeare”;

“What are the albums of the Beatles”; and

“What are the albums of Justin Bieber”.

Identification module 118B determines that the name of the author or the artist from a book or an album is the search subject because that is the common token property among all the predictive search terms.

At 208-214, operation of the interface module 118C is depicted. At 208, interface module may display a user interface which displays the predictive search sentence and displays the search subject differently compared to other terms among the predictive search terms. In an embodiment, interface module 118C may display the predictive search terms and insert a blank space instead of the search subject. In other embodiments, the relative position of the search subject (in relation to the other words of the predictive search term) is highlighted as illustrated by highlight 306 (alternatively, blank space 306) in the user interface 304.

In the present embodiment, the interface module 118C displays the predictive search terms and displays the search subject differently by displaying a blank space as illustrated in FIG. 3. The user interface 302 is displayed, in this embodiment, with multiple blank spaces (such as blank space 308) in order to indicate the search subjects. It should also be noted that in this embodiment, interface module 118C also provides three possible sentences (i.e. sentences 310, 312, and 314) as options for the user to pick.

At 210, interface module 118C may present the user with an option to modify the predictive search sentence (which comprises the predictive search terms) by modifying the search subject. The option to modify may be presented to the user by providing a blank space to the user to input the search subject by typing the word or any other electronic method such as speaking into a microphone. In other embodiments, interface module 118C may provide a list of search subjects for the user to pick.

In the present embodiment interface module 118C provides blank space 306 for the user to input the search subject. In the present embodiment, the user inputs the word “Hemingway” using a keyboard.

At 212, interface module 118C may receive the user's modification of the search subject. In this embodiment, the word Hemingway is received by the interface module 118C.

At 214, interface module 118C may display the sentence to be searched. This sentence comprises the original search terms (initially input by the user), the predictive search term (provided by the search engine), and the modified search subject (provided by the user). Interface module 118C may also communicate the sentence to be searched to a search engine.

In this embodiment the full sentence to be searched (i.e. sentence 304) is displayed by the interface module 118C. The full sentence, in this embodiment, is “what are the books written by Hemingway”. This sentence comprises the “what are” (initially typed in by the user), “the books written by” (provided as the predictive search terms by the search engine), and “Hemingway” (provided by the user as the modified search subject).

It must be appreciated that, even though the present embodiment depicts the operation of the Predictive Term Modification Program 108 as comprising only one search subject, other embodiments may comprise multiple search subjects.

FIG. 4 depicts a block diagram of components a computer system, for example server 112 and computer 102, of distributed computing environment 100 of FIG. 1, in accordance with an embodiment of the present invention.

Based on the foregoing, a computer system, method, and computer program product have been disclosed. However, numerous modifications and substitutions can be made without deviating from the scope of the present invention. Therefore, the present invention has been disclosed by way of example and not limitation.

FIG. 5 is flowchart, which depicts the operational steps of a method 500 for a Predictive Term Modification Program 108, in accordance with an embodiment of the present disclosure. In reference to FIGS. 1A, 1B, 2 and 3, steps of the method 500 may be implemented using one or more modules of a computer program, for example, the Predictive Term Modification Program 108, and executed by a processor of a computer such as the computer 102.

At 502, the receiving module 118A may receive a set of words from a user or an electronic input source for use in a search, using an online search engine. Receiving module 118A may receive the word(s) from a user or a computer implemented system. Non-limiting examples of an input source may be spoken words, typed words, or inputting a corpus electronically from a computer implemented source such as an electronic device (e.g. cell phones, tablets, or other electronic devices with speech recognition programs). Receiving module 118A may also communicate the words received to a search engine. Furthermore, receiving module 118A may receive a set of predictive search terms from the search engine.

At 504, identification module 118B may generate predictive search terms. In one embodiment, identification module 118B may generate one or more predictive search terms based on the received search terms based on statistical data collected based on previous online searches.

At 506, identification module 118B may, using the predictive search terms, may identify a search subject within the predictive search terms. In one embodiment, identification module 118B may identify the search subject by identifying search domains of the associated predictive search terms. A search domain may refer to a domain, category of search, or database, that may be typically used to search for the predictive search terms. These search domains may indicate the search subject. Identification module 118B may identify the search domains. In various embodiments, “what is the email of ______” may result in a search in some rolodex or a yellow pages, “what books did ______ write” may result in a search in Wikipedia, or “what is the status of ticket to ______” may result in a query to a ticket-purchasing application or ticket providing sites. Therefore identification module 118B may use the search domains to identify the search subject by identifying the commonality of categories between the sites by analyzing the commonality of the indexes and categories of all the sites. For example, in one embodiment, when the search term of “what is the status of flight to Zurich” results in a query of many air travel sites, identification module 118B may identify that the word “Zurich” is the search subject because all search domains have cities and destinations in common. Because the word “Zurich” is a city/destination, it is consistent with the commonality among the search domains; based on this information, identification module 118B may identify “Zurich” as the search subject. In one embodiment the search domains sites are included within the predictive search terms as metadata and identification module 118B analyzes said metadata.

In another embodiment, the search engine can progressively retrieve search results and analyze the results to dynamically identify the search subject. Identification module 118B may, decompose the received predictive search terms into tokens and may use the tokens to determine the search subject. A token may be a short piece of text or a fragment of a sentence usually comprising of words. A word may be defined, in one embodiment, as a smallest element that may be uttered in isolation with semantic or pragmatic content (i.e. literal or practical meaning). Non-limiting examples of a token include nouns, adjectives, and pronouns. Identification module 118B may analyze each token for various semantic properties. Identification module 118B may analyze the tokens and determine the search subject based on the common semantic properties of each token, sentence structure of the predictive search terms, and common properties of the tokens among all predictive search terms. For example, in one embodiment, the predictive search terms may comprise the following:

What to expect during month 1 of pregnancy;

What to expect during month 2 of pregnancy;

What to expect during month 9 of pregnancy;

After decomposing the terms into token and analyzing these tokens, identification module 118B may determine that the month number is the common token among all predictive search terms and therefore the search subject (i.e. a search subject search sentence of what to expect during month ______ of pregnancy).

At 508, interface module 118C may generate instructions to communicate the predictive search to the user. The presentation of the predictive search subject to the user is explained above at paragraph 0042.

At 510, interface module 118C may receive a modified search subject from the user. The receiving of the modified search subjects is explained in more detail, above.

At 512, interface module 118C may conduct an online search based on a modified search sentence comprising the original search terms (initially input by the user), the predictive search term (provided by the search engine), and the modified search subject (provided by the user). Interface module 118C may also generate instructions to display the search results to the user.
